Abstract :
In order to understand mechanisms of oculomotor control systems, an oculomotor model based on eye´s anatomical structure and physiological mechanism is developed. In this model, various types of eye movements are considered, and two learning systems, one based on adaptive characteristics of flocculus and other on vestibular nuclei´s are developed. The role of neural paths into flocculus from ocular muscle stretch receptors, which were thought to not contribute in eye movement, is discussed in detail from the viewpoint of system control engineering. The experimental results through simulation show good control performance of the proposed model.
